Abstract
The invention discloses a concrete brick and a manufacturing method of the concrete brick, wherein the concrete brick comprises the following raw materials by weight: 30-60 parts of waste magnesia carbon brick, 10-25 parts of coal cinder, 10-15 parts of broken stone, and 1-10 parts of plaster and/or lime. The manufacturing method comprises the following steps: hydration: 1) sprinkling the waste magnesia carbon brick with water to ensure brick to be completely wetted, sprinkling again after 10-20 hours, and standing for 10-20 hours; 2) mixing: mixing the hydrated magnesia carbon brick with other raw materials, adding water with amount of 20-60 percent of the weight of raw materials in mixing process, and pressing to brick blanks; and 3) drying: drying the brick blanks until the moisture content of the brick blanks is lower than 15 percent to obtain the concrete bricks. According to the method, the magnesia carbon bricks and coal cinders which are commonly used in industrial production are used as main raw materials, the building bricks with higher strength can be made by reasonably formulating and adopting a proper method, thus not only lightening the pollution of industrial waste slag to the environment, but also adding new material for building engineering.
Description
Technical field
The present invention relates to building material field, specifically is that a kind of concrete is laid bricks and preparation method thereof.
Background technology
Magnesia carbon brick is the maximum refractory materials of current steelmaking equipment usage quantity, because the high temperature properties of steel-making environment often has a large amount of magnesia carbon brick waste materials to produce, how making full use of the discarded magnesia carbon brick that produces in the steelmaking process has become urgent problem.And in industrial production, particularly in the Steel industry, often produce another kind of industrial waste---cinder again.Discarded magnesia carbon brick and cinder are Powdered more, are easy to produce airborne dust when waste residue is met wind during stacking, can cause serious pollution to surrounding enviroment.If adopt land-fill method to handle, can increase a large amount of waste residue transport charges and landfill expense again, particularly can occupy a large amount of land resources.
Summary of the invention

By the parts by weight of raw materials that said concrete is laid bricks, the making method that concrete is laid bricks is following:
1) aquation: toward discarding direct spray water on the magnesia carbon brick, guarantee that brick all drenches, spray water once again after 10～20 hours, placed then 10～20 hours;
2) mix: with the magnesia carbon brick after the aquation and other raw materials mix, add the water of raw material weight 20%～60% in the mixing process, be pressed into adobe then;
3) oven dry: the water cut of adobe is dried to water cut below 15%, promptly get concrete and lay bricks.
In the above-mentioned making method,
The water that mixes appropriate to the occasion adding raw material weight 50%.
Dry and appropriate to the occasionly under 150～200 ℃ condition, carry out.
Compared with prior art; A kind of concrete of the present invention is laid bricks and preparation method thereof; With discarded magnesia carbon brick common in the industrial production and cinder is main raw material; The method that suits through batching and employing rationally makes very high for building the laying bricks of intensity (can reach more than the 20MPa), has both alleviated the pollution of industrial residue to environment, has added novel material for construction work again.
